ADIABATIC COMPRESSION OF REAL GAS
Abstract
A variation in natural gas temperature in the centrifugal injectors of compressor stations is analyzed. It is commonly assumed that this process has a polytropic nature, the power index in the polytropic relation being different from the adiabatic exponent. Taking into account the transported gas real properties demonstrates that gas compression in the compressor station centrifugal injectors presents a thermodynamic process fairly close to the adiabatic one and the influence of the irreversibility and gas heat exchange with the surrounding equipment plays a significantly less role than it was thought earlier.
